From the question, there were 2 Krispy Kosmos at $2.89 unit price. Thus the cost of 2 Krispy Kosmos = 2 x $2.89 = $5.78. Therefore, total price of all items bought = $5.78 + $3.19 + $2.99 = $11.96 Sales tax = 5.8% of $11.96 = 0.058 x $11.96 = $0.69 Therefore, Total to be paid = $11.96 + $0.69 = $12.65
